Tagscanner

TagScanner is a free Chrome extension for anyone working with Adobe
Tags (Launch). Open it on any live site running Adobe Tags and get an
instant, complete view of the property — rules, data elements,
extensions, dependencies, and custom code — with no API credentials,
no backend access, and no admin rights required.

It reads directly from the _satellite container object that Adobe Tags
injects into every page. That object is always there. TagScanner just
surfaces everything inside it.

WHAT YOU CAN DO

Audit — Browse every rule with its events, conditions, actions, and
custom code. Sortable, searchable, paginated. No more opening rules
one by one in the Launch UI.

Analyse — See full data element usage tracking: which rules reference
each DE, which extensions use them, and DE-to-DE dependency chains.
Deep Scan detects ghost dependencies — data elements referenced in
custom code that don't exist in the compiled library.

Visualise — Flow Diagram generates an interactive visual map of your
entire property — data elements, rules, extensions, and the
connections between them. Always reflects the current published
library.

Search — Global Code Search runs full-text search across every rule,
data element, and extension including all custom code blocks, with
line-level match highlighting.

Export — One-click .xlsx export of every rule, data element, and
extension including custom code. The export Launch itself can't give
you.

Debug — Environment Override redirects the live Tags library to dev
or staging at the network level. No proxy tools. No test pages. No
page changes required.

AI-POWERED FEATURES (Preview / Beta)

AI Property Health Scan — A–F health score for your entire property
with an executive summary, category scores, critical issues, and
ranked recommendations. A manual audit that takes hours: this does it
in under a minute.

Custom Code Explanation — Plain-English breakdown of any custom code
block: what it does, what data it reads, what it returns, risks, and
ready-to-run debug commands.

Ask AI — Natural language questions about your live property. "Which
rules fire on page load?" "What data elements use the data layer?"
Answered instantly with conversation persistence.

Note: AI features are available on a best-effort basis. Core features
are fully available with no restrictions.

WHO IT'S FOR

Tag managers, analytics engineers, MarTech consultants, and

time on the actual work.
